HEDDLE FRAME.

Application led September 10, 1927. Serial No. 218,640.

permit the bars to be quickly and con-A veniently mounted in and dismounted from the frame when desired.

In US. Patent No. 1,486,189, dated March 11, 1924, there is shown a device for supporting the heddle bars intermediate their ends which permits the bars to be easily and con-V veniently inserted in and removed from the 2O heddle frame.

My present invention contemplates certain improvements in the device shown and described in the Letters Patent above mentioned, whereby thevsupporting device ymay be adjusted with respect to the top and bottom rails of the frame, so that the heddle sup' porting bars will be properly positioned and the heddles will not bind on the supporting bars, `or on the other hand be permittedtoo 3e great an up and down movement thereon.

The nature and characteristic features of my present invention will be more readily understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which:

Figure 1 is an elevational'view of a heddle frame provided with heddle bar supporting devices embodying the main features of my present invention; Fig. 2 is a fragmentary detail thereof, en-

larged;

Fig. 3 is a sectional view taken approximately on the line 3 3 of Fig. 2, the parts being shown in the normal positions-assumed while supporting the heddle bar;

Fig. 4 is a similar view, but with the parts in the open position for.y the purpose of removing or mounting the heddle bar therein; and Fig. 5 is a perspective view of a slidable locking member constituting one'of the elements of the present invention. I

end of the heddle frame and arranged near the top and bottom rails 10, in the usual manner, are the heddle supporting bars 12, on which the heddles 13 are mounted in the customary manner.

. The devices comprising the novel portion of the present invention are mounted at suitable locations on the inner edges of the ,top and bottomrails 10. y f On the inner side of the rail 1 0 there is provided a recess in which is seated a nut 14. rl`he shank of a bolt 15 is threaded in the nut 14. The bolt 15 extends through the rail 10 beyond the outer edge thereof. Upon the eoi end of the bolt 15 there is mounted a Wing nut- 16, and if desired, a'floclr washer 17 of any f preferred type may be interposed between the wing nut 16 and the outer edge of the rail 10.

The other end of the bolt l5, which projects toward the interior of the frame, is provided with a flattened portion 18, to which a plate member 19 is secured by rivets 20./ The plate member 19 is provided with recesses21, which are adapted to receive and support the heddle supporting bars 12.

Slidably mounted with respect to the plate 19 is a lock member 30, which is provided with a central longitudinal slot j31. The rivets 20, 'for securing the plate 19 to the head portion 18 of the bolt 15, extend through the slot 31, and the enlarged head portion 22 of said rivets 20 serve to maintain the lock memloer 30 in proper .slidable relationship with respect to theplate member 19. The lock member 30 is also provided with lip portions 32, which are adapted, when t-he lock member 30 is in the operative position, to eX- 'as at 33, being provided with an aperture 34 in the bent over portion. The smoothportion ofthe shank of the bolt 15 passes through the aperture 34 above mentioned.

' Mounted on the boltfl is a coil spring 40,

which is arranged between the bent over portion 33 of the lock meinberjBO and the nut 14 which is seated in the recess. If desired, a

washer 41 may be interposed between the end of the spring 40 and the bent over portion 33 of the slide member 30, to afford a better bear- 5 ing for the end of the spring 40.

The movement of the lock member 30 under tension of the spring 40, is limited by the longitudinal extent of the slot 31, the respective ends of the slot encountering the rivets ateach end of the movement.

The operation ofthe device may now be i readily understood. The supporting device being mounted in the heddle frame at desired locations upon the top and bottom rails thereof, and the heddle bars'with the heddles mounted thereon being placed in the frame in the usual manner, with the ends thereofsecured in position in the side strips 11 of the frame by fastening devices of any preferred type, the lock member 30 is then manually pushed to the open position as shown in Fig.

= 4 of the drawings.

Theheddle bars 12 are now inserted in the 'recesses 21 provided in the'plate member 19` and thereafter thelock member 30 is released and permitted to return, under tension of the spring 40, to the normal locking position as shown in Fig. 3 of the drawings, being therel after 'held inl` that position by the coil f spring 40. The lipportion 32 of the lock member 30 will now serve to maintain the he-ddle bars 12 within the recesses 21 of the plate member 19, and will securely hold the same against dis- 35 placement during the operation of the loom. When it is desired to remove the heddle supporting bars from the supporting devices,

it will be necessary merely to again push and hold the lock member 30 in the position shown Y 40 in Fig. 4 of the drawings, and the heddle bars 12 may then be readily disengaged from the supporting devices.

Should it be found at any time that the heddle supporting bars are so located that an undue tension is placed upon the heddles,

whereby theksame will bind upon the heddle supporting bars, or on the other hand, should it be found 4that the heddle bars are so positioned that the heddles are permitted too much up an-d down movement in the frame,

the proper adjustment of the device for supporting the heddle'bars may easily be made by irst removing the heddle bars from the supporting device, then loosening the 'wing nut '16, then threading the bolt 15 in or out with vrespect to the nut 14 until the recesses 21 in the plate member 19 are brought to the proper location, after which the wing nut 1G may again be tightened on the bolt 15. While the plate member' 19 is shown as provided with two recesses 21, for use in a heddle frame of the duplex type, in which y pairs of heddle supporting bars are arranged side by side, it will, of course, be understood thatthe device may, if desired, be s'o arranged as to support singlebars at the top and bottom rails, respectively, of., the frame, in which event the frame 19 will be lprovided with but a single recess and the slide member will be correspondingly shaped.

' It will be seen that with devices constructed as hereinbefore described, the heddle bars will be efficiently supported intermediate their ends and undue lateral movement of the same will be eectively prevented. Adjustment of the supporting devices with respect to the top and bottom rails may be quickly and eonven' iently made, so that the heddl-e bars may at all times be properly positioned.

Having thus described the nature and characteristic features of my invention, what I claim as new,-and desire to secure by Letters Patent, is a 1.
